Hand-stamp



y'UNITED STATES PATENT OEEIGE.

ALBERT J ONES, OF BUFFALO, NEW YORK.

HAN D-STAMP.

To all whom it may concern.-

Be it known that l, ALBERT JoNEs, ot' the city of Buffalo, county ofErie, and State of New York, have invented a certain new and ImprovedHand-Stamp or Dating-Machine; and I do hereby declare that thefollowingis a full and exact description thereof, referenceI being hadto the accompanying drawings, making a part of this specification, inwhich Figure I is a side elevation ofiny said stamp. Fig. II is a planofsame. Fig. III is a front end elevation, and Figs. IVand Vdetailsofchan geable die.

This improvement relates to that class of hand-stamps in which theimpression is given through an inked ribbon; and it consists, irst in anautomatic reversible feed-motion for said ribbon, whereby theimpression-surface is constantly changed and clear and uniform impressions secured; second, in securing the changeable dating-type withinthe die by a rod passing through the die and catching into notches inthe side of the type.

Letters of like name and kind refer to like parts in each of thefigures.

Arepresents the base-plate ofthe stamp, and B B a double-curved arm orbracket, the one part, B, being cast on the base-plate, the other part,B', to which the die, the., is secured, being hinged to the part B, asshown at b2, and provided with a hand-plate, B3, by which it is presseddown to give the impression, vibrating on bzasa center. The upwardmovement of this arm is given by a spiral spring, b4, connected by oneend to the arm B, and by the other to the arm B'. The arm Bhas adownward proiection, B5, which forms the diesOcket, to receive and holdthe die C.

D Dl represent ribbon-spools arranged one in front and the other behindthe die-socket B5, and having bearings in the side plates, E, secured tothe die-socket. The inked ribbon F is wound on these spools, passingfrom one to the other, over the face of the die O.

Gr represents a ratchet-wheel on the. end of the spindle of spool D, andG a similar ratchet-wheel, but with reversed teeth, on the end of thespindle of spool D.

H represents a spring-pawl, secured to the stationary arm B by athumb-screw, h', which may be made to engage with the teeth of eitherratchet-wheel, as desired, by loosening said thumb-screw and reversingits angle, as shown by the red lines on the drawings. This pawlbeingsetin position to engage with the ratchetwheel G, the spool D willbe rota-ted the length of one tooth ot' the ratchet-wheel at everyimpression, and the ribbon be wound by such rotation froln the spoolDonto the spool D, and the impression-surface of the ribbon therebyconstantly changed. After the ribbon is in this manner all unwound fromthe spool Dl it may be rewound thereon by reversing' the pawl, so thatit may engage the ratchet-wheel G', which will rotate the spools in theopposite direction.

Irepresentsafriction-spring,bearingagainst the ratchet-wheels withsufficient force to give the required tension to the ribbon.

, The die O, Figs. 1V and V, has a mortise cut through it for thereception ofthe dating-type. These are held in place by a small wire orrod, O', passing through the die alongside of the type and catching innotches O2 formed in sides of said type.

By withdrawing this rod the dating-type may be readily removed andothers substituted, as occasion requires.

This device and the stamp, as a whole, will be found very simple andconvenient for the purpose intended, also very compact and durable.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The combination and arrangement, with the inked ribbon and spools, ofthe ratchetwheels G Gr and reversible pawl H, in the manner and for thepurpose described.

2. The combination of the mortised die O, notched dating-type O2 andretai nin g-rod O in the manner and for the purpose described.

3. The double-curved arm or bracket B B', the one part stationary andthe other movable, and carrying the die and ribbonspools as described.

ALBERT JONES.
